I te 16 o Tīhema, i pānuitia e POSCO ka haumi $830 miriona ki te hanga i tētahi tipu lithium hydroxide i Argentina hei hanga rauemi pākahiko mō ngā waka hiko. E ai ki ngā pūrongo ka tīmata te hanganga o te tipu i te haurua tuatahi o te tau 2022, ā, ka oti, ka whakamahia hoki i te haurua tuatahi o te tau 2024. Kia oti, ka taea e ia te whakaputa i te 25,000 tana o te lithium hydroxide ia tau, ka taea ai te whakatutuki i te hiahia whakaputa ā-tau o te 600,000 waka hiko.
Hei tāpiritanga, i whakaaetia e te poari whakahaere o POSCO i te 10 o Hakihea tētahi mahere hei hanga i tētahi tipu lithium hydroxide mā te whakamahi i ngā rauemi mata e rongoatia ana i roto i te roto tote o Hombre Muerto i Argentina. Ko te lithium hydroxide te rauemi matua mō te hanga cathodes pākahiko. Ki te whakaritea ki ngā pākahiko lithium carbonate, he roa ake te ora ratonga o ngā pākahiko lithium hydroxide. Hei whakautu i te pikinga o te hiahia mō te lithium i te mākete, i te tau 2018, i riro i a POSCO ngā mana keri o te roto tote o Hombre Muerto mai i a Galaxy Resources o Ahitereiria mō te US$280 miriona. I te tau 2020, i whakaū a POSCO kei roto i te roto he 13.5 miriona tana o te lithium, ā, i hanga tonutia, i whakahaerehia hoki tētahi tipu whakaaturanga iti i te taha o te roto.
I kī a POSCO tērā pea ka whakawhānui ake i te tipu lithium hydroxide o Argentina i muri i te otinga o te kaupapa me te whakahaere, kia piki ake ai te kaha whakaputa ā-tau o te tipu mā te 250,000 tana anō.
